Bought the 20W great Item with all the cables and bits you need. Used it to keep Lead/Acid battery charged in my tinny for the lights, bilge pump, and sounder. Worked really well for 10 mths - until I sunk it in salt water (doesn't work well after being underwater...). Will be replacing it with another same for the tinny and an additional 30W unit to keep the winch battery charges on the dock.

Bought to top up the battery on my tractor, working great for that. One of these days I'll fix the alternator wiring, for now this solar charger keeps it going
